Andre Drummond looked poised to become one of the best centers in the NBA two seasons ago, but that all changed last season.

After earning his first All-Star appearance during the 2015-16 season, while also finishing that season All-NBA third team, the 7-foot Pistons center struggled to find consistency last season.

Drummond finished the 2016-17 season averaging 13.6 points and 13.8 rebounds per game, but he shot an abysmal 39 percent from the free throw line, while also looking slow and timid on defense.

"It was a roller-coaster ride for me and an inconsistent year for us as an organization," Drummond said, via The Detroit News. "We were really hot and cold, and dealing with Reggie (Jackson) being injured was tough to get adjusted to Ish (Smith) right away.

"My play wasn't where it was supposed to be and I take responsibility for that as well; I wasn't playing up to my potential - and I can't allow that to happen again."

Drummond, who will turn 24 later this month, underwent sinus surgery earlier this year, and he feels the procedure will help him rediscover his form.

"I'm not going to play with a filter anymore; I'm going to play the game I need to play to be a great player for my team," Drummond said. "I feel like I'm in great shape and I can actually breathe. I don't get tired as easily and I'm sleeping better. Everything has been a plus since I got that surgery."

The Pistons finished last season 37-45, which kept them out of the playoffs. This offseason, they traded Marcus Morris to the Celtics for shooting guard Avery Bradley, who will instantly be the team's best perimeter shooter and defender.

If Drummond is able to replicate his 2015-16 season, this Pistons could throw their name into the mix in the Eastern Conference.
